摘要： A new top-loading transverse connector of the present invention for bridging between longitudinal members of a spinal fixation system implant. The transverse connector is loaded and clamped to the longitudinal member from the top permitting easy access and adjustment and may clamp at the same location along the rod as a vertebral fixation element. The transverse connector comprises an elongate body and an engagement portion on each opposing end of the elongate body. The engagement portion includes downward legs each with a surface to engage the longitudinal member. The downward legs are displaced from each other to define a space therebetween. The engagement portion includes an upper surface defining an opening therethrough. The opening intersects the space defined between the downward legs. Together, the space and opening are configured to receive the clamp assembly carried on the longitudinal member. Another object of the invention, is to provide an improved system including the transverse connector. Another object of the invention is to provide a transverse connector that clamps to the longitudinal member at a variable angle. Another object of the invention is to provide a separate engagement portion which can be used with existing transverse connectors to permit clamping at the same site as vertebral fixation elements. Another object of the invention is to provide a way to adjust the length of the elongate body of the transverse connector.
摘要翻译： 一种用于桥接脊柱固定系统植入物的纵向构件之间的本发明的新的顶部加载横向连接器。 横向连接器从顶部装载和夹紧到纵向构件，允许容易地进入和调节，并且可以沿着杆作为椎骨固定元件夹紧在相同位置。 横向连接器包括细长主体和在细长主体的每个相对端上的接合部分。 接合部分包括各自具有与纵向构件接合的表面的向下的腿。 向下的腿彼此移位以限定它们之间的空间。 接合部分包括限定穿过其中的开口的上表面。 开口与下方的腿间限定的空间相交。 一起，空间和开口构造成接收承载在纵向构件上的夹具组件。 本发明的另一个目的是提供一种包括横向连接器的改进的系统。 本发明的另一个目的是提供一种以可变角度夹紧纵向构件的横向连接器。 本发明的另一个目的是提供一种单独的接合部分，其可以与现有的横向连接器一起使用以允许在与椎骨固定元件相同的位置处夹紧。 本发明的另一个目的是提供一种调节横向连接器的细长主体长度的方法。
